1907. Serial No. 361,272.

To all whom it may concern:

Be it known that I, THOMAS C. SI-IEEHAN, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented a new and useful Reversible Mold, of which thefollowing is a specification.

This is a division of my application for patent filed December 7, 1906,Serial No. 846,749.

This invention relates to a casting apparatus for casting slugs or pigsadapted to be employed in linotype or monotype casting machines and thelike.

The principal objects of the invention are to provide efficient andconvenient means for receiving the metal in reversible molds which areheld in position in a simple manner and can readily be inverted todischarge their contents and present another set of molds in position tobe filled, and generally to improve and simplify apparatus of thischaracter.

Reference is to be had to the accompanying drawings for a representationof one embodiment of this invention, in which,

Figure 1 is a front elevation thereof. Fig. 2 is a plan of the same.Fig. 3 is a side elevation, and Fig. 4 is a sectional view showing howthe mold is cooled.

On a base 10 is mounted the crucible furnace 11 or the like with whichthe invention is to be used. It preferably has a crucible having anozzle or pouring spout 27 of any desired kind.

In order to receive the discharged metal, projections 50 on the base 10are so arranged as to carry a pair of brackets 51 which have bearingsfor supporting cylindrical hubs 52 on a reversible mold 53. These hubsare traversed by water pipes 54, one of which supplies cooling waterfrom any convenient source and the other dis charges it. In order toprovide a tight joint for the water pipes a packing gland 55 isprovided, as will be readily understood. One of the packing glands has aflange with a pair of V-shaped notches 56 and on the correspondingbracket is located a spring 57 having a V-shaped projection to engagethese notches.

The mold is provided with handles 58 for inverting it and with moldcavities 59 and 60 on opposite sides. These mold cavities may be of thesame shape and character on two sides or otherwise. In the formillustrated, the cavities 59 are comparatively shallow and are designedto form slugs or pigs for use in monotype machines, while the cavities60 are of larger size designed to form slugs or pigs for linotypemachines.

The bottom of each mold cavity is preferably provided with grooves toleave the word Linotype, Monotype, or the like on the bottom of the pigcast therein.

In case the mold is provided with mold cavities on more than two faces,a corresponding number of notches 56 will, of course, be employed. Whenone side of the mold is filled and the metal is sufficiently set, thehandle 58 is grasped and turned, the shape of the notch 56 and thespring 57 being such that while suflicient resistance is presented toprevent accidental inversion of the mold, it will permit it to bepositively turned over without necessitating any setting of the oarts.hen the mold is completely reverse the other notch is in position toreceive the spring and the mold is held up ready to receive its nextcharge. The casting may be received on the floor or in a movablereceptacle placed between the brackets 51.

By the construction of the casting apparatus on the principles set forthabove, whether in the exact form illustrated or not, but within thescope of the claim, it will be seen that an eflicient way of receivingthe molten metal, cooling it, and discharging the castings, is provided.

While I have illustrated and described a particular form in which myinvention may be embodied, I am aware that many modifications may bemade therein by any person skilled in the art within the scope of theclaim. Therefore, I do not wish to be limited to the particularconstruction shown and described, but

What I do claim is In a casting apparatus, the combination of supportingbrackets having bearings, an invertible mold journaled in said bearings,said mold having a plurality of sets of mold cavities, one of saidbearings being provided my hand in the presence of two subscribing witha flange having V-shaped notches Witnesses. therein corresponding innumber to the number of sets of mold cavities, and a spring 5 adapted toenter said notches and hold the Witnesses:

mold. S. W. AIGAR,

In testimony whereof I have hereunto set D. A. SI-IEEHAN.
